Title: Improvements in or relating to joints for concrete structures
IPC: E04B1/68
Filed: 1940-03-01
Abstract: 546,701. Walls. TATE, A., and ROSE, N. R. March 1, 1941, No. 2781. [Class 20 (iv)] The joints between concrete slabs are sealed by strips 11 which are not embedded in the concrete, but are clamped thereto by bolts 8 or the like, sealing material 10 being interposed. Bars 13 may also be clamped to the strips by the boltheads. The strips are preferably corrugated at one or more places to allow for expansion and may be flat to lie on the slab-end surfaces or channelled to rest in channelled ends in the slabs. The channelled strip may have flanges turned over and bolted to the top surfaces of the slabs by additional bolts at right angles to the bolts 8. Slots 5 on the slab surface receive the bolt shanks; the heads, together with washers 9, are received into deeper slots 6. Members 28, Fig. 14, are placed in the moulds for forming the slab recesses 5, 6.

Title: Improvements in steam generators and hot-water boilers
IPC: F22B21/34
Filed: 1951-02-05
Abstract: 734,262. Water-tube steam boilers; hotwater boilers. BOUELLAT ENGINEERING, Ltd., and BAUER, F. W. May 5, 1952 [Feb. 5, 1951], No. 2818/51. Classes 64 (1) and 123 (2). A water-tube steam boiler or hot-water boiler has a furnace chamber 1 with walls and roof formed by closely spaced water tubes 2, 4, 6, 9 which may be provided with heatconducting fins and which extend between distributor headers 3, 7, 10 and an upper steam or hot-water drum 5. Alternate tubes in the upper part of the furnace rear wall are offset at 91 to provide a screen through which furnace gases flow into an open downpass 14 extending the full height of the furnace. The downpass is bounded on one side by the tubes 9 and on the other by the foremost row of tubes 12 which form the convection-heated section of the boiler. The gases turn in a soot &c. chamber 15 and rise through a pass in which are disposed the remaining tube rows of the convection section, the tubes in each row extending from lower headers 10 to upper headers 11 which are connected to the drum 5 by pipes 24, 25. Baffles 21 in the convection section cause the ascending gases to flow in a sinuous path, two of the baffles having hinged portions forming dampers whereby at low loads the convection section can be by-passed by part of the gases. From the convection section the gases flow through a downpass in which is disposed an economizer 32a, 32b. In a modification, Fig. 2, not shown, the downpass 14 is divided by a vertical, tubulous partition, one part housing a superheater whilst the other constitutes a dampercontrolled superheater by-pass.

IPC: B62D7/22
Filed: 1928-01-31
Abstract: 309,255. Bailey, E. Jan. 31, 1928. Steering-gear.-Means for preventing steering wobble comprises an adjustable friction pad carried at a fixed distance from the front axle and bearing against the track-rod connecting the stub axle steering-arms. In the construction shown a plate A is adjustably clamped to the front axle (not shown) by a plate C and three bolts G and carries an arm B having an upturned end provided with a friction pad D adapted to bear against the track-rod. A protecting sheath J is fixed to that part of the rod against which the braking device acts. The arm B is adjustably secured to the plate A by bolts F co-operating with slots, and is so situated that the friction pad bears against the track rod when the steering gear is in the straight ahead position; when the wheels are steered in either direction the track-rod moves away from the brake pad and the steering-gear is left quite free. According to the Provisional Specification the arm B may have its end carrying the friction pad spring-loaded.

Title: Machine for affixing tabs to articles
Inventor: MEYER HANS
IPC: D06F93/00
Filed: 1950-02-07
Abstract: 695,708. Labelling machines. POLYMARK, Ltd. Feb. 5, 1951. [Feb. 7, 1950] No. 3185/50. Class 73. In a machine for affixing tabs containing or consisting of thermoplastic material to laundry, etc. by pressure between heated platens, the tabs are severed from a roll by a scissor knife 5, Fig. 3, and gripped by a gripper 9 mounted on a reciprocating carrier 10 which stops under a printing head 18 comprising drums rotatable in grooves 20. The gripper 9 then passes to a nozzle 30, supplied from a reservoir 31 by a pump 33, which sprays the tab with a solvent to which water is added, and then to the heated applying platens 40, 54, Fig. 4. The upper platen 40 is mounted on a plunger 58 reciprocated by a rocket arm 63 having positive movement derived from cam followers 64, 65 while the lower platen has a rounded under side resting in a cup 55 to allow for irregularities in the work being operated on. The water added to the solvent is to prevent the tab from sticking to the heated upper platen by the generation of steam during the pressing and to allow for the escape of this steam a face plate 49 has holes 50 communicating with horizontal grooves 52. A roller 43, Fig. 5, on a spring urged arm 42 co-operates with the gripper to hold the tab as the platen descends so that pins 41 pierce the tab and locate it positively, the gripper 9 being simultaneously opened. The various parts of the machine are operated in timed relation from a common cam shaft 8 which completes one cycle on depression of a pedal or movement of a device extending over the lower platen or operation of a device incorporating a photo-electric cell. A device for holding over an edge of the tab strip before severing is described and a modified bottom platen is spring loaded. In place of the cylinders in the printing device an impression plate may be used. Specifications 561,989, 644,119 and 668,305 are referred to.

Title: Method for the separation of wax from crude wax and bitumen
IPC: C10G73/00
Filed: 1947-02-10
Abstract: Saponifiable waxes and resins are separated from crude waxes or bitumens containing saponifiable waxes and resins by heating the crude wax or bitumen dissolved in a saturated aliphatic alcohol or a compound thereof having a boiling point below 100 DEG  C. with an alkali metal hydroxide, and cooling the mixture to cause insoluble wax acid soaps, wax alcohols and any wax hydrocarbons present to separate out from the alcohol while the resin soaps remain in solution.  The insoluble waxy substances are then removed from the solution and mixed with an excess of a dilute aqueous solution of a water-soluble acid having a greater affinity than the wax acids for the soap metal, thereby liberating the free wax acids, which together with the free wax alcohols and any wax hydrocarbons are removed from the aqueous solution and treated further in a known manner.  The resin soaps and other resinous substances and any higher alcohols and hydrocarbons which are soluble in cold alcohol are recovered from the alcoholic solution and extracted either with water or with an organic solvent such as benzene.  For the purpose of obtaining wax products resembling natural waxes, the separated wax acids may be esterified with higher alcohols from the process and/or of some other origin. It is stated that any asphaltic matter settling out from the alcoholic solution after saponification and cooling does so in the form of a solid cake which can readily be separated from the precipitate of wax-like products.  In an example, bitumen obtained from an extraction process is dissolved in ethyl alcohol and saponified under pressure with potassium hydroxide.  The mixture is then cooled, the precipitate of potassium salts of wax acids, &c. which forms, is filtered off, washed with ethyl alcohol, mixed with water, an excess of sulphuric acid added, and the precipitate of free wax acids thereby formed separated from the aqueous solution.  The resinous substances which have remained in solution in the original cold alkaline alcohol solution are recovered by distilling off the alcohol and extracted with benzol.  The unsaponifiable portion dissolves in the benzol while the potassium salts of the resin acids remain as a residue.  After the separation of the benzol solution of the unsaponifiable portion, the resin acids are liberated from their potassium salts with sulphuric acid.  The unsaponifiable portion is recovered from the benzol solution by distilling off the solvent.  In the other example the resinous substances are recovered from the alkaline alcohol solution (after saponification and separation of the wax-like substances) by distilling off the alcohol and extracting the residue with cold water which dissolves the salts of the resin acids. The resin acids are then liberated from the aqueous extract with sulphuric acid.  The residue insoluble in cold water constitutes the unsaponifiable portion of the resinous substances.  Specifications 5999/00, [Class 91], and 402,751 are referred to.
